amazing!By Dannyon 9/17/2011

This was the first hanna I tried. I now want every hanna test kit that is available. This thing is super easy and gives you such a pin point reading, no more guessing!

No faster than adding drops, but not having to guestimate or ask my wife what color is the match is far nicer.

It's GreatBy Greyon 8/24/2011

Finally able to check something without mixing a bunch of chemicals. It's easy to use, and accurate. What more do you need? The only problem I had with my tester was that the tester flip top lid is very tight and difficult to open without using your fingernails, but I am sure it will loosen over time. I am just thrilled that about not having to pay 40 to 70 dollars for 25 liquid chemical phosphate laboratories anymore.

Great Product!By Chadon 8/24/2011

I bought this to keep my Phosphates in check since color card tests are inaccurate and VERY hard to read. I must say that I am impressed with the accuracy! Several tests on the same water sample resulted in the same numbers over and over.

My only real problems with the unit is the lid is VERY hard to open. If you have short fingernails or arthritis you make have problems getting the lid open. Another other problem is the reagents. I really wish they were in liquid form, it is hard to pour the dry powder in the tiny opening of the vial.

Finally the automatic shutoff timer of 2 minutes between C1 and C2 is much too fast! The powder does not dissolve quickly enough and you risk ruining the test if the unit times out. A more lengthy time period is needed here if dry powder reagents are going to continue to be used.

Other than these small problems the Hanna Phosphate Checker is genius!

Best phospate testing periodBy Richardon 7/30/2011

There is no other way to go. My local reef store recommend the Hanna, I ordered it, and there is no going back. Just be sure to follow instructions on keeping cuvettes clean, unscratched, and not introducing bubbles when testing. Standard test kits cannot be relied on, the Hanna is the way to go.

This is easily the best piece of testing equipment I've bought in years, accurate to three decimals. 0.015 target.

Hard to know how accurate the measurementBy Joeon 6/24/2011

This one is hard to know how accurate its measurement really is. I got different results even with same water sample. And of course that 3 min. timeout is crazy, lost a few package because of that.

More accurate and easier to read!By Daveon 6/16/2011

Since purchasing this checker I no longer need to ask my girlfriend to help match the colors of the test kit. My salifert test reads 0 when this reads .02-.04, which explains the slight algae problem I still have.
